Logitech G Driving Force Shifter currently on sale at EB Games for $59 + Shipping. This is no where near the all time low for it, but it is currently the cheapest you can get it from most retailers.
Compatible with PC, XBOX, PS4 and designed to be used with Logitech's G923, G29 and G920 steering wheels. EB Games also seems to be having a sale on the steering wheels as well but it seems to be quite a standard 'sale' price according to price hipster.
Click and Collect was available as an option for the store I went to and it should be easy to price match elsewhere.
What's with the G29 steering wheel? Retail prices seemed to have gone up since 4 years ago.
